Abstract
OBJECTIVE: To determine whether women with recurrent evidence of cervical insufficiency (CI) and with a history-indicated cerclage (HIC) placed at the beginning of the second trimester will deliver later than the index case. STUDY DESIGN: Retrospective case-control study of singleton pregnancy with history-consistent CI. Patients had a cerclage placed between 12 and 16 weeks of gestation. Transvaginal cervical measurement was done between 18 and 24 weeks. Those with a cervical measurement ≤25 mm were considered to have recurrent CI (Group A). Gestational age at delivery of the index case (Group C) and the cerclage patients (Groups A and B), which are the same patients as Group C, was compared using Student’s t test. They have the same genetics and anatomy. RESULTS: A total of 124 women had an HIC. Sixteen (13%) had recurrent CI (Group A). Comparing cases, the proximate average age at delivery was 22 weeks as compared with 33 weeks and 3 days for those with a cerclage (p<0.001) (Group A vs. B). In those with a cervical length >25 mm (Group B), 96 (89%) had a term delivery. In the index cases 64% delivered at 22 weeks or less (Group C). CONCLUSION: Cerclage in those patients with recurrent CI has a significantly improved outcome as compared with the index case. This minimizes pregnancy loss.
